My company wants to compare pricing on hiring a full time switchboard operator versus outsourcing to an answering service.  We have one published number for the company even though all departments have a DID line.  The company is against automated attendant so the current choices are 24/7 answering service versus hiring an operator.  The idea is that the company main number would be forwarded to the answering service who would take the call and answer as "companyname."  They would then transfer the call to a DID number at our company to complete the call.  Obviously, the answering service would have a directory of DID numbers to forward to.

I am looking for some answering services that people have tried and have been happy with.  I just want to get an idea on pricing since we'd be comparing it to hiring a full time employee.

Please provide me with a URL address of the Sprint PCS add a phone program.

I know several users who all currently have a single Sprint PCS cell phone and are interested in finding the details of how they can add a second phone to their Spring PCS account using the current Sprint PCS promotion that we have heard is going on until the end of June of 2017.
Need to run direct burial CAT5E with telephone signal lines and intend to terminate with RJ11 plugs.
I find that the wire insulation diameter is a bit large to assemble the cable end into the plug.  
I suppose that I could terminate the CAT5E cable with a modular jack and then use a telephone cord (RJ11-RJ-11) from there.
Yet, the same issue isn't anticipated on RJ45 plugs.
Is there a wire diameter (including insulation) specification for RJ11 that's smaller than for RJ45?
Does anyone know why the switch slows down so much that the VOIP starts to have Jitter and after a reboot it works fine for a week again. The switch runs the PC's through the Phones. There are no VLAN's programmed at the moment. The switch is stock standard. Are there any settings I can change?
Hello all,

I have some Win 2012 3cx v15 phone systems and was having trouble with apple push notifications for calls to remote devices.  I've determined it to be a TLS issue.  I had used IIS Crypto to remove the less secure SSL 3.0, TLS 1.0 and 1.1, leaving just TLS 1.2 and more secure ciphers.  This breaks apple push notifications from the 3cx server/software.  I put back TLS 1.1, no luck.  Put back TLS 1.0, now push notifications work.  I find it odd that I should still need 1.0 enabled on the server.  

Is apple push still using that protocol and not 1.1 or 1.2, or might there be something else going on here.

I'm by no means familiar with protocols/ciphers, just determined what fixes the problem.

I am hoping to set up call forwarding on our Samsung officeserv

I have looked at all the call forwarding options, 60? but they do not work.  

I note that this method will not override any pre-set forward settings nor will it work for groups.

Does anyone have any idea on how to make sure these things are not happening so call forwarding works?

i have a US samsung android phone bought from verizon with a local malaysian celcom SIM card.  I updated my google play to indicate that i am in Malaysia. my friend is having the same issue with another samsung phone model also US fomer verizon phone with a celcom SIM.  

But i'm getting error messages that certain malaysian apps like yonder are not available based on my country.  some of them don't even appear for me to click on. the sim card vendor tech support offers no advice.

We are looking into Skype for Business as our VOIP system. SB is seems working OK on voice side but we are struggling to find solution for paging system for classroom.  We currently suing voip phone system as paging system and will be out once we remove our pbx system out of building.  Any suggestion? Thanks for all of you in advance.

I learning up about Skype Enterprise Voice and it's potential for mobile.

Right now, we use Skype for Skype-to-skype calls. I'm wondering if this can be integrated with the telephone line in the office.  And then, if we can deploy a Skype mobile client to user's personal devices that has their office number....this way, we can :

1. A user never has to give out their personal mobile number, only their office number which will now ring on their personal phone

2. A user can make voice calls, either internally or externally, using this Skype client and reduce cost to them since it presumably uses the corporate network where possible, e.g. for international calls.

Some questions.

1. Is Enterprise Voice the term for the integration of Skype with the phone network

2. When we refer to the Phone Network, do we mean PSTN?

3. Is there a way for an enterprise Skype mobile client to have an external dialler feature so the user can phone anyone, either internal or external?

4. Are there potential cost benefits of this Skype client connecting to the corporate network

5. Is it possible for Skype mobile to have the user's office desk number so that it provides the fixed mobile convergence i talked about? Or does it need a separate number?
We use twilio and sonic firewall in the company for our voip phone system.
And the issue is packet is drop more frequency and do not know what is the issue.

Most of the drops came from inbound calls.

Twilio has no issue.

I am a newly enshrined Telco Admin for Clark County Washington and need some help modifying
the dialing plan on 8 NEC 2000 phone systems.  They are finally instituting 10 digit dialing here
in a few months and need to make the appropriate changes to the 2000's to accommodate this.

Is there anyone who would like to make a few $$ consulting or assisting in the changes necessary.
Or can someone recommend a vendor who still supports these boat anchors??

  • Have a deployment of 3 servers using dns loadbalancing.
  • we have a trunk setup via an sbc.
  • users have deskphones (CX600)

both inbound and outbound calls work as expected.

however, when a call is placed on hold after 30 seconds the call drops.

the same thing occurs when a call is parked..also after 30 seconds the call drops.

i should mention MOH IS SETUP in this deployment, however when an external call is parked there is just a beep sound.

when a call is parked between users MOH does work and the call does not get dropped.

refer and bypass are set to false on the trunk as well.  Trunk settings

in the snooper log i see references to "this call leg has been replaced"  in the same message as the BYE:
ms-diagnostics-public: 10026;reason="This call leg has been replaced";component="MediationServer"

the trace from the sbc shows that the mediation server is dropping the call so i haven't mentioned that here.

have the snooper trace if needed.

any suggestions appreciated.
How do I go about moving from a phone number hosted with to Google Voice?
Hello Experts,

I have ARM board linux and I established offline access point (using USB dongle) to connect my laptop with ARM board. The IP is
On the same ARM board I have mobile 3G connection to the internet (SIM card with dynamic IP). My purpose is to allow my laptop to connect to the internet via 3G.
What should I do? Do I need to set some routing or gateway?

Thank you.

I quite often make visits to buildings where there is no Wi-Fi I can utilise. In the meetings, I'd like to be able to use my laptop and have it connected to my work VDI.

I have a personal MacBook Air with a USB port. What is the best solution to have in order to connect to a 3G/4G connection via Cell to provide me internet access at an efficient price? Since I am actually connecting to my work VDI, this will only be light browsing traffic, no downloads or anything.

Thanks in advance.

Can anyone point me in the right direction? There are a few google hits for this problem, so it seems like a known issue.

///////Summary: On outbound calls, we are sending out caller ID, and it is showing as "restricted" on HD enabled mobile phones only. Older mobile phones and land lines display our caller ID correctly. The telco PSTN providers have all pointed to our call manager as not providing the correct 1TU-T E.164 standard. This is occurring on all 5 MGCP gateway PRI's across multiple local PSTN providers.

///////System Parameters
We have 2 call managers in our HA cluster, 1 publisher, 1 subscriber.
Cisco Unified CM Administration

System version:

VMware Installation: 2 vCPU Intel(R) Xeon(R) CPU E5-2609 0 @ 2.40GHz, disk 1: 80Gbytes, 4096Mbytes RAM, Partitions aligned

///////Troubleshooting Steps
Here is the support forum posting of the same issue, I have performed the changes advised in this posting with no success:

1) Under Service Parameters - Clusterwide Parameters - Calling Party Number Screening Indicator

Set this value to Callmanager Provides Calling Number (No success)

2) I have performed the changed to Call routing information - Outbound calls, tested with Calling Party IE type as both "national/ISDN", Calling Numbering plan "ISDN". No success.

Here are our test call DNs appearing in the debug isdnq931:
